l' lEET DELIVERY ANDVFOLDiNG MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 361,376, dated April19, 1887.

Serial No. 201,902. (No model.)

To all whom it may concern.-

Be it known that I, WALTER Scorn, of Plainfield, in the county of Unionand State of New Jersey, have invented an Improvementin Sheet Deliveryand Folding Mechanism. for Printing-Machines, of which the followingis aspecification. r

In printing newspapers it is often desirable to fold two separate sheetsand then bring the two folded sheets together with the folds adjoiningeach other, and fold them together so as to inclose the inner. foldedsheet within the outer folded sheet. This object I accomplish by myimprovement, so that a paper of sixteen pages,or any other desirednumber, is delivered from the folding-machine, and when it is desired todeliver two eightrpaged papers from the same folding-machine it isaccomplished by the adjustments without varying the parts themselves. T

In the drawings,Figure 1 is a diagrammatic view 'of the folding devicesin a plane at right angles to the axis of the cutting-cylinders, andFig.v 2 is a diagrammatic elevation of the parts at right angles toFig. 1. Figs. 3 and 4 correspond generally to Figs. 1 and 2 5 but therollers and belts are arranged for modifying the ac-' tion of thefolder.

The web of papers, after being printed, passes to the cylinders 1 and 2,and by the knife 3 the paper is perforated at the line be tween onesheet and the next, and the tapes 4 5, passing around the rollers 6 7,convey away the sheet.

The cylinder or roller 8 and the rollers 9 12 13 14 15, when placed asshown in Fig. 1, cause the belts or tapes 4 to pass up over the rollers8 and 15,down below the rollers 12 13, along horizontally around theroller 14, and thence return below the roller 9 and around the roller 6.The tapes or'belts 5pass up over the roller 8, below the roller 12, upover the roller 20, along horizontally beneath the roller 11, and returnback over the roller and beneath the roller 7. V

The tapes 4 and 5 are speeded to run faster than the web of paper, andthe advancing end of each sheet is nipped between the belts 4 and 5 asthey pass up over the roller 8, and in so doing the separation of onesheet from the next is completed,as usual in printing-presses. Below therollers 11 and are the rollers 21 and 16, with tapes 22 passing aroundthe same and over 20. These belts 22 are adjacent to the tapes 5, andthere is a switch at 23 v between the rollers 12 and 15, and this switchis moved so as to direct one sheet off between the belts 5 and 22 andthen to allow the next 1 sheet to pass down between the belts 4 and 26.It is to be understood that the rollers or cylinders 12 and 15 are to becomposed of pulleys or grooved rollers,in order that the switch 23 maybe swung beyond the line of the respective belts in either one directionor the other to deflect the advancing ends of the sheets.

first in one direction and then in the other.

The belts 26 pass around the guide-rollers 30 and 32, as well as belowthe roller 13, and the sheet which is deflected downwardly between thebelts 4 and 26 is carried beneath the roller13 and taken offhorizontally toward the rollers 14 and 32, and there are fences or stopsat and 36 to, arrest the movement of the respective sheets, so that theupper sheet may be folded by the rollers 40 and 41 when the center ofthesheet is carried down between said rollers by the folding-blade 42, andthe lower sheet may be folded by the rollers 44 and 45 when the centerof the sheet is carried down between said rollers 44 and 45 by thefolding-blade 46.

One of the special features of my present invention relates to thedevices for bringing the sheets from the folding-rollers 40 and 41 tothe same folding apparatus that takes the sheets from the rollers 44 and45. With this object in view I provide the folding-rollers and 51 andthe folding-blade 52, and the sheets, after being folded, as aforesaid,are carried to these folding-rollers 50 and 51 and beneath thefolding-blade 52 by tapes or belts, as next described.

The belts or tapes pass around the folding-roller 41, around and beneaththe roller 61, along to the roller 62,and around the same, and returnbeneath the roller 63 to the roller 41. The ranges of tapes or belts 65pass around the roller 40,beneath the roller 61, along horizontally andbeneath the roller 66, and return beneath the roller 67 up to the roller40. There is a range of deflecting-fingers, 70, and guidebars 71. Thedeflecting-fingers 70 turn the fold of the sheet toward the roller 62and over.

the rollers 50 and 51 after the blade 46 has folded the center of thesheet down between the rollers 44 and 45, and the sheet is carried alongupon the belts 60 and beneath the fold ing-blade 52 and stopped by thefence 7 2. The sheet that is folded by the blade 42 between the rollersand 41 is carried down by the belts or tapes 60 and 65, around andbeneath the rollers 61, along beneath the rollers o'o,and beneath theguide-bars 71, and over the folding-rollers 50 and 51 to the fence 72.

The folding-blades 42, 46, and 52 are to be actuated by any suitablemechanism such as levers and cams or other weltknown devices* and theseparts are to be movable, so that the respective folding-blades can beactuated at the proper times.

If one sheet is to be laid upon another, the parts are to be timed sothat the sheet that is folded between the rollers 40 and 41 passes alongupon the belt 60, and receives upon it the sheet folded between therollers 44 and 45, so that the folded edges coincide and reach the fence72 together, the sheet folded between 44 and 45 being laid upon thesheet folded between 40 and 41, and in this condition the sheets arestopped against the fence 72. The blade 52 is now brought down and theimposed folded sheets are folded together and passed off by the rollersand 51 into a delivery-box, or the sheets may be folded again by rollersand a blade at right angles to the rollers 50 and 51, if desired, and asillustrated at 80 81, Fig. 2.

If the sheets are to be discharged separately, instead of lying oneupon'the other, (and thereby deliver, say, an eight-page paper insteadof a sixteen-page paper,) it may be accomplished by timing thefolding-blades 42 and 46 in such a manner that the folded sheets willpass along in succession to and beneath the folder 52. In this case itwill be necessary to give to the blade 52 two reciproeations to eachmovement of the blades 42 and 46; but if the folding-blade 52 issufficiently long, or is made in two parts, as seen in Fig. 2, thesecond folded sheet may pass beneath the blade 52 in the rear of thefirst one, so that the two sheets can be folded at the same time withoutlying one upon the other.

The foregoing description is generally applicable to the devices shownin Figs. 3 and 4, as well as to those shown in Figs. 1 and 2. In Fig. 3the roller or cylinder 8 is placed higher up than it is in Fig. 1, andthe switch 23 acts between the rollers 8 and 12, and the rollers 15 and16 are dispensed with, and the belt 26 is preferably guided by anotherroller, 31. The operations of these parts are the same; but in Fig. 1the two sheets have the ditional to those shown in Fig. 4- and beforedescribed, are made with reference to adjusting the action of the parts.

The tighteners 83 85 are preferably ranges of pulleys set upon swingingcrank-arms upon cross-shafts, and the roller 84 is for adjusting theparts. By varying the position of the adjusting-roller 84, the lengthsof the belts and between the folding-rollers 4O 41 and the guides and 71will be varied and the adjustment made so that the distance traveled bythe sheet as folded between 40 and 41 will insure the arrival of thefolded edge of the sheet at thejunction of 70 and 71. at the same momentas the sheet folded between 44 and 45 arrives at the same place; henceone sheet is properly laid on the other.

The tighteners S3 and are adjusted to give the proper tension to thebelts after the guide-roller 84 has been-properly placed. Aguide-roller, 86, serves to keep the tapes 65 clear of the folder 46.

When it is desired to fold the two sheets separately, the roller 84 isproperly placed so that the distance traveled by the respective sheetsbrings the end of one sheet to the fence 93 at the same time that theend of the other sheet reaches the fence 72, so that the folders 52 and52 can be brought down together in folding the sheets.

\Vhere the sheets are folded separately, the blade 52 acts upon one atthe same time as the folder 52 acts on the other. A folder, 90, androllers 88 89 are used to fold the sheets that receive one fold by theblade 52", if so desired.

It will beunderstood that this sheet-delivery apparatus is especiallyuseful in printing-offices where a variety of work is done, because itcan be used to assemble and fold into one all the sheets or pages thatare printed at one revolution of the press, or to deliver themseparately with one or with two or with three or more folds.

It is usually preferable to employ the belts 91 around the guide-pulleys92 94 95, to convey the sheet along in connection with the belts ortapes 60, and these tapes 91 may go over the roller 44, Fig. 2, insteadof over the roller 98, Fig. 4.

\Vhen the folder 52 is used, a fence, 93, Fig. 2, should be provided toarrest the sheet; but this is turned up out of the way when the sheetsare laid one upon the other and folded by the blade 52.

If desired, the cylinder 8 may be provided with any of the known meansfor imposing one sheet upon another, so that the sheets may bedischarged in pairs to pass to the folding devices described, in whichcase the type-cylinder may be four times the size of thecuttingcylinders, so that the products of the two folders will be onecomplete paper or signature.

I claim as my invention- 1. The combination, with the longfoldingrollers 50 and 51 and the separate foldingblades 52 and 52, oftwo sets of folding rollers and tapes, one set including the tapes 60,to bring a folded sheet to one end of the folding-rollers 50 51, and theother set to bring the other folded sheet to the middle of suchfolding-rollers 50 and 51, the two folded'sheets being moved in the samedirection by the tapes 60,that are parallel with the said rollers 50 51,and the deflector 70 and guidebars 71 and the movable fence 93, wherebythe apparatus is adapted to laying one folded sheet upon another andfolding them together, or of folding the sheets separately,substantially as set forth.

2. The pairs of folding-rollers 40 41 and 44 45 and their respectivefolding-blades 42 and 46, and the ranges of belts for conveying thesheets to such folding devices, in combination
